Take one bool variable and one integer variable for page number like this:

var isDataLoading = false
var pageCount:Int = 1 // Pass this page number in your api

in cellForItemAt method add below code:

if !isDataLoading && indexPath.row == videoViewModel.count - 1 {
            isDataLoading = true
            pageCount += 1
// add you api call code here with pageCount
        }

once you get your data from api set isDataLoading bool to false like below:

self.isDataLoading = false
